Use CLI11 parser for all native benchmarks

[bibikar]

This PR attempts to resolve some inconsistencies in argument parsing in native benchmarks, and uses CLI11 parser globally for native benchmarks. It also refactors distances, linear/ridge regression, and kmeans benchmarks to use some common code for consistency.

• Add CLI11 header to repo
• Combine cosine and correlation distances into one file
• Use CLI11 in distances, linear/ridge regression, kmeans benches
• Pass around results of benchmarks for verification if needed (as NumericTablePtr or ResultPtr or std::tuple)
• General refactoring of benches converted to use CLI11 for easier readability
